INSECTS OF SAMOA 

AND OTHER SAMOAN TERRESTRIAL 
ARTHROPODA 

Although a monograph, or series of papers, dealing comprehensively with 
the land arthropod fauna of any group of islands in the South Pacific may be 
expected to yield valuable results, in connection with distribution, modification 
due to isolation, and other problems, no such work is at present in existence. 
In order in some measure to remedy this deficiency, and in view of benefits 
directly accruing to the National Collections, the Trustees of the British 
Museum have undertaken the publication of an account of the Insects and other 
Terrestrial Arthropoda collected in the Samoan Islands, in 1924-1925, by 
Dr. P. A. Buxton and Mr. G. H. E. Hopkins, during the Expedition of the 
London School of Hygiene and Tropical Medicine to the South Pacific. 
Advantage has been taken of the opportunity thus afforded, to make the studies 
as complete as possible by including in them all Samoan material of the groups 
concerned in both the British Museum (Natural History), and (by courtesy of 
the authorities of that institution) the Bishop Museum, Honolulu. 

It is not intended that contributors to the text shall be confined to the 
Museum Staff or to any one nation, but, so far as possible, the assistance of the 
leading authorities on all groups to be dealt with has been obtained. 

The work will be divided into eight " Parts " (see p. 3 of wrapper), which 
will be subdivided into "Fascicles." Each of the latter, which will appear as 
ready in any order, will consist of one or more contributions. On the 
completion of the work it is intended to issue a general survey, summarising 
the whole and drawing from it such conclusions as may be warranted.

MICRO-LEPIDOPTERA. 

By Edward Meyrick, B.A., F.R.S. 

Hardly half-a-dozen named species of Micro-Lepidoptera were recorded from 
Samoa before the receipt of the present collection, by which the total number is 
raised to 137. Out of this whole number thirty are found also in Papuan, 
Australian, or extra-Pacific regions, and it is probable that the whole of these 
are introduced by man through ships, though in some cases the actual habits are 
not yet known ; seventeen are found in other islands of Polynesia (excluding 
the Papuan region), but not elsewhere, and these also are probably transferred 
from one group to another only by man, though they may be capable in some 
cases of passing without help from one island to another within the same group ; 
and the remaining ninety are all endemic. These numbers are practically in 
the ratios of 6:1:2; that is, jj ? or § of the species are endemic, and of the 
remaining third, § belong to other faunas and ^ are of strictly Polynesian origin. 
These proportions are likely to be maintained for a considerable period ; I am 
satisfied that a large number of endemic species remain to be discovered, but the 
importation of species will still go on at a proportionate rate ; in Hawaii, where 
careful observations have been made by the resident entomologists for a number 
of years, it is found that, notwithstanding the peculiar isolation of that group, 
fresh imported species are continually turning up. These ratios prove unques- 
tionably that Samoa constitutes, by the test of specific endemicity, a perfectly 
distinct and isolated faunal region. 

The relation of this fauna to others must be studied through the genera. 
The total number of genera is seventy-nine, but twenty-five of these are only 
represented by apodemic species and may be disregarded ; the ninety endemic 

species are then distributed in fifty-four genera, which also include sixteen of 
in (2) 1

the apodemic species, or 106 species altogether. This is an abnormal ratio, 
being an average of barely two species to the genus, but the proportion of species 
to genera will probably be materially increased by further collecting, though 
it is necessarily always low when the total fauna is small. Of these fifty-four 
genera only eight, belonging to six distinct families, are endemic, and these are 
all monotypic ; therefore, isolated as the group is, it cannot in a biological sense 
have been isolated very long. If we compare Hawaii, with a very prolonged 
history of permanent isolation, we shall find that most of the principal genera, 
rich in species, are endemic, and some of these so peculiar that they have no 
near relatives elsewhere ; the endemic genus Hyposmocoma contains 190 species. 

Taking the remaining forty- two genera in order of magnitude, we find : 

Labdia, seventeen species, all endemic but two ; a considerable Indo- 
Malayan genus, also freely colonising Australia ; the larvae are refuse-feeders, 
and the islands are apparently well suited to them, the genus being equally 
prominent in Fiji and the New Hebrides. 

Decadarchis, nine species, of which seven are endemic ; this genus, of 
which the larvae also feed on refuse and dead wood, is probably Indian by 
origin, like the last, occurring also in the African and Malayan regions and in 
Australia, but apparently attaining its greatest development in the South 
Pacific islands. This and the preceding genus have the obvious advantage of 
being able to find suitable larval food in any island that they can reach ; they 
alone show considerable specific development, probably due to this suitability 
rather than to any special earliness of colonisation. 

Hiero?nantis, five species, of which two occur also in Fiji ; a small Indo- 
Australian genus, probably also a rabbish-feeder. 

Acrocercojjs, five species, two of these imported ; a very large cosmopolitan 
(but especially Indian) genus ; the larvae mine in leaves, usually of trees and 
shrubs. 

Thiotricha, five species ; a considerable Indo-Australian genus, larvae 
case-feeders on leaves of plants. 

Eucosma, four species, one of these introduced ; this very large genus is 
cosmopolitan, but especially characteristic of the Northern hemisphere, not 
much developed in the Indo-Malayan region, and very little in Australia and 
New Zealand. 

Stathmopoda, three species : a large genus, mainly Indo-Australian, the 
larvae mostly rubbish-feeders. 



MICRO-LEPIDOPTERA. 



G7 



Opogona, three species, related together and probably developed from a 
single immigrant form ; a considerable genus, cosmopolitan in warm latitudes, 
but specially Indo-Australian, the larvae feeding on dead vegetable tissues, and 
probably often having relations with Termites, sometimes feeding within their 
nests. 

Spilonota, three species, one of these also in Fiji ; Indo-Malayan by origin, 
but with more specific development in Australia, the larvae being commonly 
attached to Myrtaceae. 

The remaining thirty-three genera include in each case only one or two 
species, and all without exception are of Indo-Malayan type, the line of relation- 
ship passing through the New Ireland group and not by way of Australia. This 
explanation covers the whole Micro-Lepidopterous fauna, nor is there any 
evidence of more than one period of immigration. 

Two cosmopolitan families, easy of observation, are absent from the indi- 
genous fauna, viz. the Pterophoridae and Oecophoridae. The Pterophoridae 
are obviously insects of very weak flying powers, but on the other hand their 
structure is apparently specially adapted to favour wide distribution by the 
wind, and in fact many of the species have exceptionally extensive ranges ; 
they are, however, as I have pointed out elsewhere, a family of very recent 
origin, and attached exclusively to the most modern and highly developed 
orders of flowering plants, and this circumstance probably accounts for their 
absence ; they have not previously succeeded in effecting a lodgment in Samoa 
or Fiji, but are now filtering in with assistance. It should be noted, however, 
that New Zealand is fairly well supplied with indigenous Pterophoridae, and 
Hawaii also has species, the source of these being probably in both cases America. 

The Oecophoridae are a much more puzzling problem. The family is one 
of the largest, being only exceeded by the Gelechiadae,* and though not one of 
the earliest, it is certainly older than the Gelechiadae. It is numerous in all 
regions, but particularly so in those adjacent to the Pacific, Australia and New 
Zealand, in each of which it is the largest family, though in the main originating 
separately, the New Zealand forms chiefly from South America, and the 
Australian mostly from India. The family is equally at home in the moist 
temperate climate of New Zealand and the dry heat of Australia ; from the 
latter continent no fewer than 1,500 Oecophoridae are already known. There

is much diversity of larval habits, but probably a considerable proportion of 
the genera feed on mosses, lichens, dead wood and bark, which would be avail- 
able anywhere, whilst even the more highly developed genera, which are attached 
to plants of special character, are not in general more exacting than other leaf- 
feeders (such for example as the Gracilariad Acrocercops, which is indigenous 
in all three regions). Nevertheless, not a single species of Oecophoridae has 
occurred in Samoa ; neither has a single one been found in Hawaii, though the 
fauna of that group is now very well known and has some remarkable analogies 
with that of New Zealand, such as the excessive development of the Pyralid 
genus Scoparia, found everywhere in New Zealand associated with Oecophoridae 
and probably often feeding on the same plants, yet in Hawaii unaccompanied. 
Hawaii can only have obtained its fauna by wind transportation over a wide 
sea, and some of its eccentricities may reasonably be attributed to chance ; but 
a striking feature like this, shared by Hawaii and Samoa, cannot be accidental ; 
there must be some compelling cause, though at present I am unable to suggest 
its nature. A single Oecophorid only has been taken in Fiji, a species of the 
Australian genus Peritorneuta. 

The larvae referred to as refuse-feeders live on a great variety of dead or 
decaying vegetable matter, such as the dead stems, leaves, or seed-vessels of 
sugar-cane, cotton, coconut, etc., also apparently on the excrement or rubbish 
left by other insects in such situations, thus acting as scavengers ; this habit 
of life is less usual in cool or dry countries, but seems especially favoured in 
hot damp climates, where such materials are naturally more liable to disintegra- 
tion. Larvae with these habits must always have had a good chance of being 
transferred from one island to another by the natives in their canoes, ever since 
the earliest appearance of man in the region. It must not be assumed that such 
insects are not injurious ; it is found in some cases that when plentiful, their 
natural food running short, they may gnaw the substance of the growing plants,, 
and damage the buds or vegetating shoots.

especially on Leguminosae and Cucurbitaceae, with, which it has probably 
been introduced. 

2. Alucita candidalis Walk. 

In 1885 I recorded the Australian A. aptalis Walk, from Samoa, Tonga, 
and New Hebrides, on specimens taken by Mr. G. F. Mathew, but I am now 
convinced that these were A. candidalis, which. I have lately seen from the 
New Hebrides, and with which I was not then familiar ; it occurs from Africa 
and India to N.E. Australia and New Guinea. There is no example of the genus 
amongst the present material.

Upolii, Apia, March ; 1 ex. Occurs from S. Africa and Madagascar through 
India, China, and Malayan region to New Hebrides and Fiji, also in N. America.

streak forming anterior margin of ocellus, and one close before termen from near 
apex to near tornus, its upper extremity connected by a stria with penultimate 
and antepenultimate pairs of costal strigulae ; a blackish longitudinal mark

only (not connate). 

Upolu, Malololelei, 2,000 feet, February, June, July ; 8 ex. I have also 
an unquestionable <$ example (somewhat larger, 14 mm.) from Ceylon, Haputale ; 
the species is therefore probably not indigenous in Samoa, but has been imported 
with its food-plant.

third are blue-leaden, others dark fuscous ; rest of costa dark fuscous with 
seven pairs of white strigulae, first two pairs emitting short oblique blue-leaden 
strigae, third a very oblique blue-leaden stria which runs to join apex of an 
erect silvery streak from tornus, fifth a curved blue-leaden striga which runs 
to apex of seventh ; from before third pair a very oblique wedge-shaped dark 
fuscous streak runs to disc at |, with a projection from middle of anterior edge ; 
from middle of dorsum a rather oblique slender dark fuscous streak terminating 
in a crescentic spot in disc, on each side of this a blue-leaden stria, some blue- 
leaden marking in disc before this ; several dark fuscous and blue-leaden marks 
in disc towards termen ; a dark fuscous spot extending along lower half of termen

Samoan Islands, but without specific locality ; 1 ex. Very distinct. 

16. Eucosma defensa Meyr. 

Upolu, Malololelei, 2,000 feet, February, April ; 9 ex., one of these bred 
from rotten breadfruit, perhaps an accidental association, as the normal food- 
habit is given below. Described (Exot. Micr. ii, 517) from a specimen from 
Fiji, also occurring in New Hebrides, but afterwards obtained freely in the 
Malay States, and probably introduced thence into the Pacific region, bred in 
both regions from larvae feeding on leaves of Pongamia and Dalbergia 
(Leguminosae). 

17. Eucosma samoana Reb. 

Described (Mitt. Naturh. Mus. Hamb. xxxii, 153, 1915) as follows (an 
abbreviated translation) : 

9 18 (19) mm. Palpi twice diameter of head. General colouring grey : 
forewings with darker striae and blackish-brown markings, consisting of a 
streak on fold from base angularly bent before middle and running to dorsum, 
a small oval spot beneath middle of costa prolonged in a black longitudinal 
streak to beneath apex, and a rounded dorsal spot before tornus ; costa dark- 
spotted, with indistinct whitish strigulae, two longer pairs towards apex more 
conspicuous. Hindwings blackish. 

The description cannot refer to any insect in this collection, and I do not 
recognise it as any species known to me. As only the $ was known, it might be- 
a Spilonota, which is in fact more probable. 



MICRO-LEPIDOPTERA.

18. Bactra microtripta, n. sp. 

cJ? 10-11 mm. Head, thorax grey-whitish. Palpi If, grey-whitish, second 
joint in one example obscurely spotted grey. Antennae minutely ciliated. 
Fore wings termen straight, $ rather oblique, $ oblique ; whitish, irregularly 
speckled fuscous and dark fuscous ; costa obliquely strigulated dark fuscous ; 
sometimes a short fine dark dash in disc about end of cell ; an almost terminal 
irregular dark line more or less expressed : cilia grey-whitish, obscurely barred 
fuscous and dark fuscous irroration. Hind wings grey-whitish or whitish-grey, 
in one $ grey ; cilia whitish. 

Upolu, Apia, Malololelei ; Savai'i, Tuasivi ; February to June, 8 ex. A 
specimen with forewings whitish-ochreous, with blackish dots on margins, some 
slight ochreous-grey suffusion on median third of dorsal area and a few blackish 
strigulae in disc anteriorly, apparently belongs to the same species. 

19. Polychrosis botrana Schiff. 
Upolu, Malololelei, 2,000 feet, July ; 1 ex. Widely distributed in Europe, 
Africa, and Australia, imported with the grape-vine, of which the larva is a 
pest, though it will also feed on several other plants. Also an example from 
the Ellice Islands ; the insect is therefore probably established in other Pacific 
islands, but is inconspicuous and generally overlooked. 

20. Polychrosis xylistis Low. 

Upolu, Apia, Malololelei, 2,000 feet ; Tutuila, Pago Pago ; June, September, 
December ; 2 ex., also 3 in Bishop Museum. Described from a type from 
Queensland, which is presumably its home ; probably introduced into Samoa 
with its food-plant, but habits at present unknown. 

21. Articolla prospera Meyr. 

Upolu, Malololelei, 2,000 feet, April, June ; 3 ex. Occurs in India and 
Australia ; habits unknown, but doubtless artificially introduced into Samoa. 

22. Argyroploce aprobola Meyr. 
Tutuila, Pago Pago, December ; 1 ex. Originally described from Tonga 
in 1886, but since found in India, Ceylon, Seychelles, Tonkin, Java, Formosa, 
New Guinea, and Australia ; probably Indian in origin ; the larva is polyphagous 
on various cultivated trees and shrubs (Mangifera, Cassia, Lantana, Nephelium, 
etc.), with which it is introduced. Recently I have seen specimens from the 
remote island of Rapa.

9 12-13 mm. Head whitish-grey-ochreous. Palpi whitish-ochreous, 
second joint with indistinct grey bar. Thorax in one specimen ochreous-whitish, 
in the other greyish with ochreous tegulae, crest sprinkled dark fuscous. Fore- 
wings termen slightly rounded, somewhat oblique ; ochreous-whitish, irregularly 
striated or marbled pale blue-grey, but leaving ochreous-whitish striae on 
margins of dark markings ; markings brown or fuscous, somewhat mixed and 
partially edged dark fuscous ; rather narrow irregular oblique fasciae near base 
and before middle variably developed ; a moderate rather oblique fascia from

29. Phthorimaea heliopa, Low. 

Rebel (Mitt. Naturh. Mus. Hamb. xxxii, 154) describes as Gelechia (Lita) sp., 
without recognising or naming it, an insect which is unquestionably this species ; 
the collection submitted to him was mostly made at light in Apia. No example 
exists in the material in my hands, but the species is a well-known pest of the 
tobacco-plant, and practically certain of introduction ; it is now generally 
distributed in India, the Malayan Islands, Australia, and South Africa.

Upolu, Apia, Vailima ; Savai'i, Tuasivi ; Tutuila (Bishop Museum) ; April 
to July, November ; 11 ex. in all. Doubtless common generally ; occurs also 
in Fiji, New Hebrides, Hawaii, Marquesas, Rapa, and apparently throughout 
the Pacific islands, but not known elsewhere, therefore indigenous in the region 
and spread through it by man. Larva on dead grass, probably also on other 
dry vegetable refuse. 

Agonoxenidae

Upolu, Apia, September (Swezey) ; 1 ex. (Bishop Museum). Described 
from Fiji (Exot. Micr. ii, 472), and also seen from the Ellice Islands ; the larva 
feeds on leaves of coconut, and the species is doubtless transported by man. 
Apparently the males are normally without the white streaks on the forewings, 
though the females possess them.

Eastern Australia, Borneo, Tonkin, India, Egypt, Seychelles, Mauritius, 
Rodriguez, Bermuda, and South America. Larva mining in leaves of Cyperus 
rotundus, a very widely distributed plant, but the insect is probably artificially 
introduced. There are, however, endemic species of Cosmopteryx in Fiji and

Upolu, Malololelei, 2,000 feet, Apia, 1,000 feet; June, October, December; 
4 ex. Extremely similar to Ph. prasinochroa, of Sydney, New South Wales, 
being identical in structure, markings, and colour, except that Ph. prasinochroa 
is apparently paler in colouring (but I have never seen fresh examples), possesses 
some black marking preceding the sinuation of the praemarginal line which is 
quite absent in Ph. bryophylla, and is without the abdominal hairpencils of 
<§. Neither species is known to me as occurring in any other locality, nor any- 
thing at all near them. The close and interesting resemblance in colour and 
details of markings to some species of Carposina indicates the real affinity 
between the families, which is shown also in all the structure except the dis- 
tinguishing neuration of hindwings.

128. Comodica lucinda, n. sp. 

7 mm. (Head missing.) Forewings light orange ; base suffused dark 
fuscous ; rather broad white suffusion along costa, narrowed posteriorly ; very 
oblique dark fuscous streaks from costa before \ and about middle reaching 
half across wing, second followed by an attenuated white streak edged blackish 
posteriorly and terminating in a blackish tornal spot ; a very oblique blackish 
streak from costa about f , curved up to apex ; a slender blackish median streak 
from basal suffusion to tornal spot ; a thick oblique blackish streak from dorsum

two or three diverging blackish lines (imperfect). (Hindwings missing.) 

Upolu, Malololelei, 2,000 feet, April ; 1 ex. Notwithstanding the imper- 
fect condition of the type, this species is so recognisable, and so obviously allied 
to but distinct from the Australian C. tigrina, that it can be safely described ; 
it is certainly interesting enough to deserve description. 

TlNEIDAE 

Marmaroxena, n. g. 

Head shortly rough-haired ; ocelli posterior ; tongue (apparently) developed. 
Antennae over 1, in somewhat stout, filiform, simple, scape short, without 
pecten. Labial palpi rather long, curved, ascending, slender, with appressed

scales, second joint with several lateral bristles, terminal joint slightly shorter 
than second, pointed. Maxillary palpi rather long, several-] ointed, folded, 
loosely scaled. Posterior tibiae smooth. Forewings lb furcate, 2 from angle, 
3 approximated, 4 absent, 5 closely aj>proximated to 6 towards base, 6 and 7 
stalked, 7 to costa, 8 somewhat approximated, 9 from angle, 10 from towards 
angle, 11 from before middle. Hindwings f , lanceolate, cilia 2 ; 2 and 3 very 
short, 4 absent, cell probably open between 2 and 5, 5 and 6 stalked, 6 to termen, 
7 nearly connate with stalk. 

Quite abnormal, but possibly having some relation with Hestiaula, which, 
however, is itself an entirely isolated form. 

129. Marmaroxena autochalca, n. sp. 

J 8 mm. Head shining dark purplish-bronze, face paler. Palpi whitish- 
ochreous. Antennae dark grey. Thorax shining dark purple-bronze. Fore- 
wings elongate, slightly dilated, costa gently arched, apex pointed, denexed, 
termen very obliquely rounded ; shining dark purple-bronze ; the deflection 
of apex produces a slight transverse brighter purple depression on costal half at 
f , and another somewhat more marked beyond this lighter and tinged golden- 
metallic towards costa : cilia dark grey, basal half blackish. Hindwings dark 
purplish-bronzy-grey ; cilia purplish-grey. 

Upolu, Apia, May ; 1 ex. This species and Philocoristis catachalca, which, 
though in no way related together, are both much modified in the same sense 
from their normal facies, suggest imitation of a common model, perhaps a 
metallic Hemipteron.

parts of Asia and East Australia to Fiji and Hawaii, artificially spread ; the 
larva feeding on a great variety of dry animal and vegetable substances. 

135. Cyathaula maculata Meyr. 
One example, stated to be Samoan, but without exact locality.
